OK...So I am getting a U010C code which I can clear and it stays off for a day or so before coming back on.
The code is loss of communication with the turbo actuator. I don't see where it could be intermittent with all the connections secure?
I wonder just how the actuator sends these codes.
1. Is the actuator being jammed by the moving vanes in the turbo being clogged and thereby sending a over amp draw?
2. Is the actuator shorting out internally?
3. Is the PCM acting up?

Hate to throw a new Holset turbo ($$$) at the problem if it is something simple.
